let there be demons

The gaping crater has been this way since 1971. when Soviet
geologists tapped into a cavern natural gas and deesdee to hum it eff so
t poison anyone. They thought it Wtflol take a few thays. Four
decades rater. locals refer to this pit as the Dearth Hell.

Here in the UK, were apparently sitting on 50 years worth of shale gas, hopefully those Russian ******* will stop putting the squeeze on the rest of Europe if we can relieve some of the pressure caused by the huge demand.

You have to setup a machine that can pressurize the steam - to do that, you have to build a massive pipe that covers the entire hole. This is how the turbines work; you need to have the steam compressed and pressurized to be focused into the turbine to spin it before you generate the steam. You can't just pour water on it, let the steam run through the turbine, and go "WIN!", that's a half-baked idea.
So no, don't do exactly what threadz said, or else you end up with a half-baked product.

...the water never leaves the pipes. It's like a circuit. The pipes travel down from the power plant into the hole, the water boils, the steam travels up a second pipe back to the power plant, turns the turbines, condenses into water, and is pumped (or moved via gravity) back into the hole to reheat.

But you need a massive pipe to capture all of the steam if you want to get the maximum efficiency value, or else you end up losing a lot of possible power and end up costing yourself more power pumping the water down the hole then you gain from gathering the little steam you can through a pipe that isn't designed specially to carry a gas.

Then you have to pressurize those same pipes to gather that steam in the first place - the steam isn't going to just travel up the pipe fast enough to produce a force for the turbines to spin with. More power.

Then you have to maintain the pressure so the steam completely transfers through the turbine and into the chamber that will be used to condense the water - which then needs another pressurization to send the water back in the loop.

So no matter what - you're going to need a large pumping system to pressurize all of the pipes. The steam isn't going to just flow into the pipe and hit the turbine with enough force to turn it.
You need a massive pipe that's going to be able to gather all the flowing steam - being that it's a gas - while maintaining a bottlenecked formation to pressurize itself and keep the steam moving at a rate fast enough to propel the turbine - all the while hoping that this generates enough power to profit from - let alone keep the pumping system going.
And don't even get me started on the maintenance.

Do you know how hard it would be to do that? Nearly impossible. If you didn't know, this hole is around 200 ft wide and is filled with natural gas... You can't just call Fire Engine 3 down from the station to put it out lol
